You can now access what used to be called the Australian Digital Thesis Program through Trove, which is the National Library of Australia's database - http://trove.nla.gov.au/[9]

..Once you are at Trove you can go to the 'Advanced Search' mode and select the format type as thesis to restrict to just that type of reference. and set the 'availability' to online to just show online theses.
